efi download/slipons

[jtpheritage]

I have a 2007 FLSTC completely stock. I was going to add the screamin eagle slipons, air filter and have the dealer give me a download. Anybody have any opinions on this? I was trying make a change on a budget.
From what I understand the newer bikes run very lean. Does anyone know if the dealer download will help this condition? Does anyone know if the fuelpak would be a better way to go to help this?

The lean running condition has been a probelm for aircooled bikes with the closed loop ECM's.

Are you having any issues with overheating now? Is the bike hot in stop and go traffic? Does it shut down due to overheat? These are all issues that I have seen on some of the closed loop air-cooled v-twins around here. They're cured by re-mapping the bike with either a SEPST or Master Tune. I like the master tune because of thier V-Tune feature. The V-Tune feature allows you to make a descent VE table without a dyno. A good dyno tune is hard to beat, but it's also hard to find a good dyno tuner. The V-Tune can get you a well mannered bike, and you can tune the rideable VE cells to allow you to have a good running, cooler bike with a safe AFR. TTS - MasterTune EFI Programming Software

Sounds like you need to install a Power Commander EX. Anytime you change the configuration of the fuel and exhaust system you need to remap the fuel injection system. Go to theirweb site for more info. I myself will be getting one next year.

Here is what worked for me on my 07' Street Glide. I put on the Screaming Eagle 50 state legal slip-on exhaust along w/ the HD high flow air filter and backing plate. Before I made those changes I installed the Cobra FI2000 fuel processor. It is a plug and play product and required no dyno time and no downloads. My bike runs excellent. No poping on decel, no heat issues (I also run an oil cooler and use synthetic). My spark plugs look good. I can sit in traffic and not feel like my motor is going to melt down. This was all accomplished for around $800. It is not the best solution but it has worked for me for 12000 miles. I hear you can make the above changes w/o adding a fuel processor. But, I also hear that power will be better w/ a processor as you can adjust the fuel ratio. Dyno time would be best (and you will know exactly what your air/fuel ratio is) but it is not in my budget. I"m not sure about the dealer download as I stay out of the dealer if at all possible. I looked at the Fuel Pak but opted for the Cobra due to ease of use. The Fuel Pak looked pretty easy but the Cobra was even easier. You will definetely get other opinions and probably better advice from other members of this site. I'm not sure what my result would have been if I did not use the fuel processor but I am very happy with the end result...plus I didn't throw a ton of cash at the bike. Good luck.

Thank you for responding. I am going to try the cobra fuel processor.
In the instructions it gives you settings. With your setup did you need to adjust the three pots at all? or did the settings cobra suggest work?
I know if I get coughing through the air filter it is a lean condition and I guess if I smell gas an overly rich mixture?
How will I know if everything is ok?
Is there anything you can suggest that the engine is properly tuned and these additions (slipons,air filter & processor) are all working together as they should?

The settings which they suggested worked for me. I played around with them to see if it made any difference for fuel consumption. I didn't seem to make a big difference. The bike shouldn't backfire on deceleration. This would indicate a possible lean condition..or any popping through the breather. I checked my spark plugs pretty regularly and found they are a very very light brown.... I also noticed an immediate reduction in heat coming from the engine. This is where a dyno would be helpful..but it is not in my budget and all outward signs indicate that my bike is running well.

The instructions Cobra provided were pretty good. However, if you have a shop manual read the section for partial removal of the fuel tank. If you don't have a manual be aware of this....You will need to disconnect the feul line from your tank. It is a quick disconnect. It is very easy to do...much like disconnecting an air line from a compressor. If you simply lift the tank you will break this connection and it will need to be replaced as it is a high pressure line. Routing the wires in the wire trough is somewhat of a pain but if you take your time it can be done neatly.

When I installed the Cobra I added it first to my stock bike w/ stock pipes...then I added the SE slip-ons and then the high flow breather....I made the necessary adjustments according to the directions as I made each change.

Hey pspt122
I really appreciate your assistance.
I wish I would have seen your reply sooner.
I would have taken your advice.
I partially installed this unit yesterday after work but ran out of light so I only got as far as installing the injector portion. I did not remove the gas tank but lifted it up as the instructions said to do. I think everything is ok. I didn't hear or see anything that may have broke. I will check when I get home and hopefully get the oxygen sensor portion installed.
I've never did this before so any advice you have I'll take it.
I cant beleive how tight everything is. Getting those injectors in, running the wires under the tank, and looking at the battery that looks like it is going to be a headache to remove to.
I'll keep you posted.

It is tight around the injectors....I forgot about that. Running the wires to the injectors is the worst part. Just take your time. Before you fire the bike up check that fuel line first. Turn on the ignition and switch the on/off switch to "on" position. Don't start the bike. If there is a leak you won't be able to miss it as its a pressurized line. Unfortunately, I don't know any other way to check that line w/o pressurizing it. If it leaks you'll have to replace it. I believe it is under $50. I had to replace mine after my daughter walked through my work area and stepped on the line which I had removed. Sorry I didn't reply sooner...life and work kept me from this site.

When your running your wire to the front oxygen sensor make sure it is not in an area where it might get pinched if you use a motorcycle floor jack.

Hey pspt122
Thanks again.
I think Im in good shape.I installed the rest of the unit on saturday & sunday.
I turned on the bike without starting it. All three lights came on for a few seconds then went out. I heard the fuel being pumped in. I didnt see or smell any gas leak so I think im ok and I started it a few times. I then started it and the green light came on only while it ran so I think Im in good shape. Yeah running that wiring was tough. Just like you said you really need to take your time with installing this unit.For anybody out there that is going to get this unit.
For the long oxygen sensor I just followed the wiring harness and zipped tied it in three places to the harness like the instructions said. It took me a few times to route that long wire because I wanted to hide it the best I could. Im very pleased the way it came out for just a regular working guy like me. Prior to this I only did my own fluid changes and adjust the clutch handle. You cant see that wire. I haven't taken it for a ride yet because I still need to install the screamin eagle air filter and slipons.Thats the next step.Im hoping to have this done by wed or thurs.
I will keep you posted.

Great! I'm glad this worked out and I could help you save a few dollars. I'm no mechanic by any stretch either. I did a lot of my own work on cars and all my bikes back in the day purely out of necessity. I'm a big believer in having a shop manual. I'll read over the job a half dozen times and either buy or borrow any tools I need to get the job done. With my 07' I'm hoping I don't run into any computer related issues or I will have to go to the dealer. I am thinking of installing a gear drive to replace the cam chains at around 25 or 30,000 miles....probably the same time I replace the lifters. There are some things like setting gear lash that I'm going to have to research before I decide if I want to tackle this job. I think I'll be ok as long as I read, plan and ask a lot of questions before I tear the bike apart. Anyway, keep me up to speed on how things are going with your fuel processor.
